Manual speed limiterPrinciple With the system, the speed can be restricted
from a value of 30 km/h/20 mph. There are no
restrictions below the set speed limit.
Exceeding the speed limit In particular situations the speed limit can be
deliberately exceeded by accelerating strongly.
The system gives a warning if the travelling
speed exceeds the set speed limit.
No brake intervention
If the set speed limit has been reached or unin‐
tentionally exceeded (for example driving
downhill) there is no brake intervention.
If you set a speed limit during the journey
which is below the current speed, the vehicle
rolls until the driving speed drops below the
speed limit.

Attentiveness assistant
Principle The system can detect increasing inattentive‐
ness or tiring of the driver on long monotonous
drives, for example on motorways. In this situa‐
tion, it is recommended that you take a break.
Note WARNING
The system does not take your personal
responsibility from you when you are estimat‐
ing your physical condition. Increasing inatten‐
tion or fatigue might not be detected, or not in
good time. Danger of accidents. Make sure
that the drive is rested and alert. Adapt driving
style to the driving conditions.◀
Function The system is switched on every time the en‐
gine is started and cannot be switched off.
After the start of the drive, the system is adap‐
ted to the driver so that an increase in inatten‐
tion or fatigue can be detected.
This process considers the following criteria:▷Personal driving style, for example, steer‐
ing.▷Drive conditions, for example, time of day,
duration of drive.
The system is active from approxi‐
mately. 70 km/h, 43 mph and can display a rec‐
ommendation to take a break
Recommendation to take a break
With increasing inattention or tiredness of the
driver, an instruction is shown on the control
display with the recommendation to take a
break.
A recommendation to take a break will only be
displayed once during an uninterrupted trip.
After a break, at the earliest another break rec‐
ommendation may be displayed after approxi‐
mately 45 minutes.
System limits
The function may be restricted in situations
such as the following and no warning or a
wrong one is triggered:▷If the time is wrongly set.▷If the speed driven falls considerably below
70 km/h, 43 mph.▷For sporty driving style, for example, with
heavy acceleration or fast cornering.▷In active drive situations, for example, fre‐
quent lane change.▷With bad road conditions.▷With high side-wind.
PreCrash
Principle With the system from 30 km/h/20 mph critical
driving situations may occur, which could
cause an accident. In these situations, auto‐
matically preventative, protective measures
are taken to minimise the risk of accident.
Critical driving situations are, for example:
▷Full braking.▷Heavy understeering.▷Heavy oversteering.
When collision warning or front-end collision
warning with braking function is fitted, within
the limits of the system, threatened collisions
into vehicles in front or stationary vehicles are
detected.
Note WARNING
The system does not take your personal
responsibility from you. Critical situations can‐
not be detected reliably or in good time due to
limitations of the system. Danger of accidents.
Adapt driving style to the driving conditions.
Observe the traffic situation and intervene ac‐
tively if the situation warrants it.◀

WARNING
When driving with a roof load, for exam‐
ple with a roof rack, the higher centre of gravity
can mean that driving safety is no longer guar‐
anteed in critical driving situations. Danger of
accident or damage to property. Do not deacti‐
vate Dynamic Stability Control DSC when driv‐
ing with a roof load.◀
Overview
Button in the vehicle
DSC OFF button
Indicator and warning lights If indicator light is flashing: DSC is reg‐ulating the acceleration and braking
forces.
If indicator light is illuminated: DSC has failed.
Deactivating DSC: DSC OFF
General Driving stability during acceleration and cor‐
nering is restricted if DSC is deactivated.
To support the driving stability, re-activate
DSC as soon as possible.
Deactivating DSC Press and hold down the button – but for
no longer than approximately 10 seconds
– until the DSC OFF indicator light in the in‐
strument cluster is illuminated and DSC OFF is
displayed.
The DSC system is switched off.
Activating DSC Press the button.
The DSC OFF and DSC OFF indicator
lights are not illuminated.
Indicator and warning lights DSC OFF is displayed in the instrument cluster
when DSC is deactivated.
If indicator light is illuminated: DSC is
deactivated.
M Dynamic Mode
M Dynamic Mode allows driving with higher
longitudinal and transverse acceleration on dry
carriageways, but with restricted drive stability.
Only in the absolute limit of the range does the
system engage for stability purposes by re‐
ducing the engine power and by brakes ap‐
plied to the wheels. In this driving situation, ad‐
ditional steering corrections may be required.
WARNING
With activated M Dynamic Mode stabilis‐
ing engagements are only carried out to a re‐
duced degree. Danger of accident or damage
to property. Adapt to the traffic conditions. Ob‐
serve the traffic situation and intervene actively
if the situation warrants it. Do not move the
steering wheel with unnecessary force in case
of warnings.◀
To support the driving stability, re-activate
DSC as soon as possible.
Activating MDM Press the button briefly.
In the instrument cluster, the indicator
lights MDM and DSC OFF illuminate.Seite 125Driving stability control systemsControls125

DSC indicator light also flashes:
M Dynamic Mode is regulating the driv‐
ing and braking forces.
Indicator lights illuminate:

Active M Differential
Principle The active M Differential blocks the rear axis
transmission steplessly, depending on the
drive situation. In so doing, even with the DSC
switched off and in M Dynamic Mode, spinning
of a single rear wheel is avoided and therefore
optimum traction is provided under all driving
conditions.
The driver is responsible for a driving style ap‐
propriate to the situation.
Adaptive M chassis PrincipleThe system reduces unwanted vehicle move‐
ments when a dynamic driving style is used or
on uneven roads.
Depending on the condition of the road and
the driving style, this enhances driving dynam‐
ics and driving comfort.
